Denis Noncarrow, who as chairman has lead the Southold Republican Party through a series of successful elections, stepped down Tuesday night, citing his desire to spend more time with his family.

“I feel it’s time,” said Mr. Noncarrow, who previously served as the party’s vice chair and treasurer. “The committee is in good shape and there’s more than enough people to take care of it.”

With the resignation, the party leadership post falls to current vice chair John Helf of Peconic. The party is expected to name a new chairman within a month.

Mr. Noncarrow has held the chairman’s position for four years. He also serves on the board of directors of Community Action of Southold Town, an anti-poverty group, and is expected to become its chairman following Peg Murphy, who is stepping down.
